Amlogic S912 is a powerful SOC (“System On a Chip“) enabling 4K video in 10 bits -or even 12 bits Dolby Vision- encoded in h265 or V9 compression engines.
HOWEVER, Rockchip RK3399 includes an hexacore processor in a Big.Little configuration. The concept behind the funny “Big.Little” naming involves an asymmetry on their core processing technologies and speed: You will find a quad core A53 Arm processor, along a dual core A72 Arm processor inside the RK3399 chipset.
The dualcore A72 in RK3399 is particularly capable, efficiently churning data up to a speed of 2.0 Ghz. The end balance is that the rockchip RK3399 is a bit faster and versatile than the S912 chipset.
It is easy to know that why Sumsang Chromebook uses RK3399 CPU, which is said to be the first time for Chinese CPU manufacturers to be accepted by international top brands.
